2 Claims. (01. 46-95) Thepresent invention consists of a Jet propeller toy, an object of which isto provide self propelled toys operable in the air, on land or in the water.

Further objects of the invention are to provide inflatable bodies of sufflcient capacity to hold an appreciable supply of air, gas or like motive agent which is emitted from the body in a predetermined volume to correspondingly effect propulsion of the body at a predetermined speed; to provide a jet propelled toy vehicle, the forward speed of which is variable at the option of the user; to provide an inflatable body the contents of which are used as the propulsion agent, replenishment of the body being effected by simple means and in a facile manner to permit recharge by a child; and to provide a jet propelled toy which may be inexpensively manufactured from readily available materials.

Other objects of the invention will be apparent from the following description of the preferred forms of the invention, taken in connection with the accompanying drawing, wherein:

Figure 1 is a side elevational view of an aerial let propulsion toy constructed in accordance wit the present invention;

Figure 2 is a similar view of a jet propulsion water toy;

Figure 3 is a similar view of a jet propulsion land toy;

Figure 4 is a similar view of a toy body or tank usable in amphibious operations;

Figure 5 is a detail enlarged fragmentary view of the aft end of the vehicle body, showing to advantage the inlet valve and the outlet openings for the jet or jets;

Figure 6 is a plan view of an apertured disc for use on the aft apertured end of the body; and

Figure 7 is a modified form of disc.

In Figure 1, I have shown a jet propelled toy generally designated 8, which is of the general conformation of an airplane, the fuselage consisting of an inflatable body equipped with a cockpit 9, lateral y extending wings l0 and an empennage II. The body is preferably streamlined, the aft end thereof tapering to a truncated terminal which is provided withone or more openings l2 around which an annular recess is formed, as shown in Figure 5. The air, gas, or other content of the inflatable body is dispensed or exuded from the latter through the opening or openings l2 to provide a jet or series of jets adapted to propel the body forwardly.

I desire to control the volume of the propulsion agent escaping from the inflatable body and to this end, I have in the drawing shown a disc l3 which may be provided with a single opening ,as illustrated in Figure 6, or a plurality of selective openings l5, as illustrated in Figure '7. The disc I3 is rotatably mounted on the aft end of the body 8 in any suitable manner for certain types of toys. However, in a preferred embodiment, I employ a valved tube l6 extending through the rear end of the body and the center of the disc l3. The tube is equipped with a standard one-way valve l1 and also with external screw threads l8 for engagement with complemental threads of a pump or other inflating agent. The threads are also adapted for the reception of a nut l9 which is used to secure the disc l3 from casual displacement. Preferably the inner face of each disc is provided with a rib 20 which engages a complemental annular recess formed in the aft end of the body 8 as-illustrated in Figure 5. The nut l9 normally holds the disc I3 in contiguity to the aft end of the body 8, When the body is inflated, an air seal is provided between the disc and the body, by use of any suitable sealing means. In a preferred embodiment of the invention, the rib 20, described supra, serves this purpose.

Although one opening, in the aft end of the body, in conjunction with the disc i3, is suiflcient for operation, it is to be understood that more than one opening may be provided, if so desired. These openings may intermittently register with a selected opening or openings in thedisc l3, to form multiple jets or sequential jets varying in volume. It is furthermore within the. contemplation of this invention to dispose the walls of the openings l4 and I5 at an angle in. order to vary the path of travel of the jet or jets.

Not only is it the purport of the present invention to simulate air, land, water and combination vehicles, but in addition, these toys may be equipped with the appurtenances necessary to each particular kind of travel, such as the sustaining surfaces l0 and guiding and steering means ll of Figure 1. Where a boat is used, as shown in Figure 2, a keel 2| and rudder 22 may be employed, and the latter, being ad- I justable at a predetermined angle if desired.

amphibious operations. It may be desired in this type of body to use a heavier and more powerful propulsion agent, introduced into the tank body through a valved opening 24, preferably arranged at the end opposite to that which carries the perforate disc l3.

I have herein described certain preferred forms of my invention but I am aware that various changes may be made therein, within the scope of the claims hereto appended.

What I claim is:

1. A jet propelled toy including a hollow body adapted for the reception of a'jet producing agent, the body being provided with a vent, a disc mounted on said body and extending over the vent to normally prevent exit of the jet producing agent, a valved tube extending through the disc and body for the charge and recharge of
